Abstract
The invention relates to a method for producing tubular containers with an open filling opening and with an end that is provided with a seal. The inventive method comprises the following steps: separately producing a preform with a neck with definitive dimensions and a tubular body with smaller dimensions than the definitive form, the tubular body containing the open filling opening; fixing the preform that is produced to a drawing head by its neck and subjecting it to at least one partial heating process; introducing the heated preform that is attached to the drawing head into the inside of a multi-part closed blow mold in such a way that the open filling opening is air-tightly held at the lower end of the blow mold; fitting a blow nozzle to the filling opening of the preform.
